Lines 445–691

The chorus recognizes the meaning of Clytemnestra's dream. They verbalize what we already know, namely, that Apollo's plan as revealed to Orestes is working out. In the final stanza of its song, the chorus shifts its focus to the crimes of Pelops, the founder of the royal family at Argos to which Electra, Agamemnon, Orestes, and Aegisthus belong. In doing so, the chorus expands on the idea of tainted natural order introduced by the images of Clytemnestra's dream, extending the unnatural roots of evil beyond Clytemnestra and Aegisthus's murder of Agamemnon, all the way back to the murders committed by the founding father of the family. Orestes's return as the natural heir hence gains even greater symbolic weight, for he symbolizes the end of the evil perpetrated not just by a single generation, but by a series of generations throughout history.
